WS-2020-0264
Good to know:
Date: May 31, 2020
Affected versions of 'sys-info' use a static, global, list to store temporary disk information while running. The function that cleans up this list, 'DFCleanup', assumes a single threaded environment and will try to free the same memory twice in a multithreaded environment. This results in consistent double-frees and segfaults when calling 'sys_info::disk_info' from multiple threads at once.
